CHROMOSOME STUDIES ON FINNISH PTERIDOPHYTA III

CHROMOSOME COUNTS OF SOME ANGIOSPERM SPECIES FROM IRAN (III)

Original meiotic or mitotic chromosome counts are presented for 17 species in 12 families of angiosperms from Iran. Chromosome counts for Amberboa nana, n=16 (Asteraceae) and Camelina rumelica subsp. transcapica, n=13 (Brassicaceae) are repoted for the first time. Chromosome numbers for six species including: Rhagadiolus stellatus (n=5), Campanula raponcoloides (n=34), Campanula trachelium (n=1...

Studies on Training Text Selection for Conversational Finnish Language Modeling

Current ASR and MT systems do not operate on conversational Finnish, because training data for colloquial Finnish has not been available. Although speech recognition performance on literary Finnish is already quite good, those systems have very poor baseline performance in conversational speech. Text data for relevant vocabulary and language models can be collected from the Internet, but web da...

CHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...

Palynological analysis of Sphaeropteris gardneri (Cyatheaceae, Pteridophyta).

The spore morphology and wall ultrastructure of Sphaeropteris gardneri (Hook.) R.M. Tryon from Brazil were analyzed with LM, SEM and TEM. The spores are trilete with an ornamentation formed of short low ridges with spines in their margins. The exospore is 2.5microm thick, two- layered in section and single or branched channels are present. The perispore is 1.2microm thick and two-layered. The i...
